Specification of Letters Patent. Patented Sept. 23, I919.

Application filed May 15, 1915. Serial No. 28,272.

To all whom it may concern:

Be it known that I, HOWARD F. SNYDER, a citizen of the United States, residing at Newton, in the county of Jasper and State of Iowa, have invented certain new and useful Improvements in .Wringers, of which the following is the specification.

Wringers as heretofore made, in so far as I am aware, are always provided with considerable mechanism, such as tension springs,

' adjusting screws, pressure bars, etc., mounted in the top of the wringer frame and projecting upwardly a considerable distance above the rolls. disadvantageous construction for the reason that such projections take up a great deal of room, require a large amount of storage space and increase shipping charges. Again,

1 these upstanding projections are unsightly and in the way and are very, apt to catch and tear the clothes of the operator. While wringers of the prior art have some times been provided with wringer release devices of various forms it has heretofore been impossible to instantaneously release the tension of the wringerrollswithout displacing various springs, pressure plates, or other parts, which must be reassembled and put back in the frame before the wringer can again be put into operative condition.

Another disadvantage of the old form of construction is that whenever the wringer is released, (if mechanism for that purpose be provided) it has been necessary not only to replace the various springs and other parts which have been displaced by the release of the wringenroll, but to each time reset the tension before the wringer can again be operated. Similarly if the tension is relieved by letting upthe springs, these springs must be tightened again and their tension reset prior to the operation of the wringer. Either of these operations con surnes so much time and is so much trouble that in actual use, wringers of the old form are generally neither released nor relieved of their tension before they are put aside after washing has been done, but are left in tension, which is bad for the rolls.

To overcome these various defects and dis advantages my present construction has been devised in which the wringer is of compact construction having no upwardly projecting parts; in which the wringer canbe instantly released Without disassembling the tension- This is an unwieldly and elements; in which the two rolls when released may be widely se arated to lay them both open to view; an release the wringer may be instantly put in operative condition without resetting or readjusting the tension means.

It is another object of my invention, to provide a wringer of simple, economical and compact construction having no parts which project high above its support to take up excessive room, or to catch and tear the clothes of the operator.

It is another object of my invention to provide a wringer in which the upper roll may be swung away and widely separated from the lower roll to lay both rolls open for inspection, cleaning or removal of any material which may become wound in them in the operation of the machine, or for other purposes.

It is another object of my invention to provide a wringer comprising two hinged arms and releasable tension means acting from below the lower arm but projecting therethrough so as to engage the upper arm and draw it downwardly toward the lower arm, whereby the tension elements of the wringer are situated and controlled from below and the upper may be swung clear without disturbing them.

It is, another object of my invention to provide a means whereby the tension ele ments when released are held in a position in which they may instantaneously reengage the wringer so as to again put it in operative condition.

Other objects and advantages of theinvention will appear as the description to.

Fig. 5 is a perspective view of the wringer closed, or in operating position, without the drain board.

Fig. 6 is a perspective vlew of the wringer in open or released position, without the drain board.

In the drawings: 1 represents a casting or bracket formed integral with the lower casin which after its ing of the. wringer. hereinafter described,

andaffording means for the attachment.

3 of the wringer to a support, the particular depending bracket 1 being only oneof set? eral ways b which the wringer may be mounted, an in this instance being designed to besecured to a swinging support so that the wringer may be swung from one positionjto another. Preferably integral with the bracket 1 is the lower housing structure comprising enlarged housings 2 for the lower wringerroll gears, the'intermediate shell portion 3 inclosing the lower wringer roll and the housings 4 to hold the'bearings of the lower roll shaft. The housings4 are substantially semicircular in form and are pro.-

' vided with reduced outwardly extending flanges 5 to protect the roll shaft. Recesses 6 are provided in the housings 4 through which project the corners 7 of the ball races 8 for the shaft of the lower wringer roll.

) These ball races 8 are pushed into the housings 4 from above and when in position are heldthe notches 6 and by the stiff resilient slightly inturned fingers 9 at the for. ward upper corners of the housings 4. The

housings 4 are integrally connected with the housings 2 by the reduced webs 10. The housings 2 are provided, as stated, to accommodate the lower gears 11 u on the lower wringer roll shaft 12, upon w ich is mount-- ed the lower wringer roll L. The shaft 12 is extended. and "key-slotted at one end to receive a handle or a driving gear as clearly shown in F' s. 1, 5 and 6. These housings 2 I arepiovide with front and rear extensions 13 and 14 having flanges projecting toward the .roll shaft,- as shown at 15-16-17 and 18, flanges 15 and 16 being separated by slots 19 for the reception of the'upper and lower roll shafts, which slots extend downwardly to the reduced web 10', as shown inFig. 1. Flanges 17 and118 are cutout, as shown at 21 and 22 for a purpose hereinafter to be described, and are provided with guard and strengthening ribs 18 and are provided with slots 20 to accommodate the lower wringer" roll shaft 12.. The front extensions 13 are, enlarged, as shown at 23, andproject ver- .tically upwardly, The rear housings 14 are flared backwardly, as clearly shown in the drawings, this construction being adopted to permit the upper half of the casing to swing into and out of telescoping relation with the lower half of the casing, as hereinafter more fully described. The shell 3 which connects the housings 2 and incloses thelower roll-L terminates at its upper sides in the integrally formed lips 24 which are integral with the extensions 25 on the 1111161 flanges 17, and project longitudinally, as indicated'at 26 to overlap these extensions, and are provided with end closures 26, all corners being rounded so as to provlde a smooth entrance or mouth in which the material to be operated isiaasi j 1 upon cannot catch. Projecting downwardly from the housing 3 are lugs or ears 27 which are slotted, as shown at 27, and provided with apertures, as shown at 28 for the reception of cotter pins to provide a bearing support for the plvots of a reversible drain board-29 which maybe used to run the water ofl in either direction.

Integrally formed with and projecting flat overhangs 37, the construction being such that when the upper arms are swung to open position, as indlcated 1n Fig. 6, the flat overhangs 37 will rest agalnst'the flat rear sides 33 of the ears 32 to hold the wringer in open position. The arms 35 at their forward ends are formed integrally with a housing construction somewhat the same as the lower housing hereinbefore described, incasing the upper wringer roll U and adapted to telescope into the lower housing to completely inclose both rolls. This housing construction comprises end housings 40 provided with reduced extend ing flanges 41 and having recesses to receive the pro ecting corners 42 of the upper ball races 43, and stiff resilient extensions 44 to lock the ball races 43 in position. The upper ball races 43 carry the shaft 12 of the upper roll U which is provided at-elther end with gears 11 meshing with the gears 11 of the lower roll shaft, to cause both 7 rolls to rotate in unison during the operation of the wringer. from the housings 40 are reduced flanges 45 integral with the top housing structures 46 for the upper wringer r611 gears. The top housing structure 46 is provided with adapted to fit into the lower housing above described. The top housings 46 close, the tops of the lower housings, as indicated in Fig. 5, flanges 45 coming down outside the flanges 15, as clearly shown in that figure. Integrally connecting the housings 46 is the caslng or shell 48 for 'thehpper roll which terminates at either end in the flat webs 50 which form the inner sides of the top housings 46 and rest in the cut away portions 21 -22 of the lower casing. Projecting from the upper casing 48 are lips 52 having rounded edges for guiding the clothes to and from the wringer roll v v The upper arms 35 are provided with em largements 55 which are countersunk, as

Projecting inwardly 1 integral depending flanges 47 which are iec . neously.

31 in the lower rolls are provided with coun-.

tersinks 31 and openings 31 centered with the, slots 58 just described. T-headed bolts 60 pass through the orifices 31 and ten sion is applied to these bolts by compression springs 63, the upper ends of wh1ch rest in the countersink 31 and the lower ends against the washers 64, adjustable by means of thumb screws 65. Collars 61 are provided upon the bolts 60 and rest upon the tops of the arms 30 to limit the downward movement of the bolts under the influence of springs 63, the space between the collars 61 and the heads 66 of the bolts 60 being sufiicient to accommodate the bottom of the countersinks 56, as clearly seen in Fig. 3. The right hand collar 61 is cast integral with a bell crank 67 and handle 67 I connected by a link 68 which is bent down:

wardly and then inwardly, as indicated at 69-70, so that its medial-portion 71 fits under the lip 24 of the lower casing and is thus out of the way, the opposite end of the link being formed in the same way, connecting with a crank 72 rigid with the collar 61 upon the opposite T-headed bolt. By this means both bolts are turned simulta- When the handle 67 is in its outward position, as shown in Fig. 5, both T-headed bolts 60 are--turned so that their heads are across slots 58, and rest against the stops 57 if closed, and the wringer is thus locked occurs in the operation of the wringer (such as the catching of the fingers of the operator between the rolls, or the winding of the clothes thereon), the handle 67 has simply to be pulled to approximatel the position shown .in Fig. 6 whereupon t e T-heads 66 of the bolts 60 will register with the slots 58 releasin the entire upper half of the wringer, w ich may'then be swung to the position shown in Fig. 6 instantaneously .releasing the upper roll and laying open both wringer rolls for inspection, cleaning, or for other purposes. When it is desired to resume operations, the upper half of the wringer is lowered, the casings telescoping, as shown in Fig. 5 to completely inclose the entire machine except for the space between the upper and lower lips 24 and 52, through which the clothes are fed into and from the bite of-the rolls. Theupper arms 35 then assume the position shown in Figs. 3 and 5 wherein the bottoms of the countersinks 56 rest uponthe collars 61, and the bolts may be turned by means of handle67' to lock the wringeragain in operative post tion. It is articularly to be noted that there is no isplacement of any springs or other mechanisms when the wringer is released. This feature I consider broadly new. It is also to be noted that no adjustment whatever is necessary of the springs 63 when the wringer is released or put back in operative condition, their tension having once been adjusted remains so adjusted 'indefinitely. I consider this feature highly important and also broadly new. The wringer when assembled is completely inclosed and incased so that there is no possi- 'bility of catching or tearing any clothes.

Moreover, when the wringer is closed the only conspicuous projection thereon is the handle 67 This is an important feature, for the operator if her fingers are caught in the rolls has only to grab the only projection in sight to be released. Where there I are several projections on the machine the operator whose fingers are caught is likely in her confusion to grasp the wrong one first and thus to be severely injured before she, releases herself. This feature I also consider broadly new. The tension means 7 opened up, as shown in Fig. 6, so that every part thereof is accessible.

Having described my invention, I claim:

1. A wringer comprising two pairs of arms hinged together, a wringer roll in each pair of arms, resilient means for forcing said pairs of arms together and a single means for instantaneously and completely releasing one pair of said arms, whereby the same maybe swung back on its hinge completely free from the other pair of arms and e releasing means.
